Numerical Analysis of Torsional Effect of the Eccentric Structure Caused by the Running Train

Article Preview

Abstract:

Application of finite element software ANSYS coupled with the train-ground dynamic model is developed to predict the torsion effect of asymmetric structure. Respectively analyze on eccentricity ratio is 0, 0.1, 0.3, 0.5, 0.7, 0.9, and 1.0. Results show that the ground vibrations by the train are slight. Eccentricity of the structure has certain effect on horizontal displacement, horizontal angle displacement, and floor horizontal acceleration.
